SlPHON-TOP.

SPECIFICATION forming part of Letters Patent No. 502,451, dated August1, 1893. Application led December I5,l 1892. l Serial No. 455,296. (Nomodel.)

To @ZZ whom t may concern:

Be it known'that I, CHARLES VVALTER,aV citizen of the United States, anda resident of Stapleton, in the county of Richmond, State of New York,have invented certain new and useful Improvements in Siphon-Tops, ofwhich the following is a specification.

This invention relates to improvements in the tops of siphons forcarbonated liquidsgand the object of myinvention is to provide a top ofthis kind in which the valve is perfectly packed and the glass tube isprevented from being broken by rough handling of the siphon.

The invention consists in asiphon-top constructed with a bot-tcm neckhaving a packing-ring in its Lipper part, a valve-stern passing throughsaid packing-ring and a cupshaped valve screwed to the lowerend of saidvalve stem below the packing-ring.

The invention also consists in the construction and combination of partsand details, which will be fully described hereinafter and iinallypointed out in the claim.

In the accompanying drawings, Figure l is a longitudinal verticalsectional View of my improved Siphon-top closed. Fig.2 is a similarview, opened, and Fig. 3 is a horizontal sectional view, on the line 33, of Fig. l.

Similar letters of reference indicate correspending parts.

The Siphon-top is made in the usual manner with the screw-neck A, thehollow stem B, the spout T, the pivoted lever C and the slidingvalve-stem D pressed upward bya helical spring E. A metal collar F,which is screwthreaded internally, is applied on the outer surface otthe neck G of the bottle or siphon G, and on the top of the Same and theupper edge of the bottle neck G a soft rubber packing ring K is placed,the neck A being provided at its top with an internal shoulder o, thatrests on said packing-ring. In the top of the neck A a packing-ring L ofrubber is held in asuitable annular recess, and through saidpacking-ringaneck M passes, that forms a guide for thelower end of thevalve stem D. The lower end of the stem D is screw-threaded, and on thesame the cup-shaped valve O is screwed, the upper open end of which canrest against the packing-ring L. The glass tube P is secured at itslupper end in a hollow head Q provided at its upper edge with the flangeR that rests between the packing-ringsL and K. The spring E normallykeeps the upper edge of the cup-shaped valve O pressed against theunderside of the packing-ringL, thus iuterruptingthe communicationbetween the glass tube P and the faucet spout T. Whenever it is desiredto draw the liquid the lever C is pressed down and the cup-shaped valveO is moved from its seat, that is, namely the packing-ring L, thuspermittingtheliquid under pressure to pass through the tube P into thehollow head Q and up through the neck M into the hollow stem D and thefaucet tube or spout T. As soon as the lever Gis released the spring Edraws the valve O up against its seat again. As the seat is made ofrubber and the edge of the valve rests on said seat, said valve closesperfectly and there is no possibility of a leak. Furthermore, thecup-shaped valve O, has the advantage that when the valve is openedsuddenly and the Water rushes' up it does not spout out of the tube Twith such great force as in ordinary spouts, for the reason that thewater trst fills the cup-shaped valve and thereby loses some of itsforce. The iiange R of the head Q being held between the rubberpacking-rings L and K has a more or less elastic supportand thusprevents the glass tube from being vbroken when the bottle is set downforcibly Having thus described my invention, I claim as new and desireto secure by Letters Patent- In a Siphon top, the combination, with a`faucet stem having a tubular neck, of a pack- .ence of two subscribingwitnesses.
